To all whom it may concern:

Be it known that I, CHARLES W. BOWEN,

bfLynn, in the county of Essex and State of trated embodiment of theinvention is effect- Massachusetts, have invented certain new and usefulImprovements in Heel-Building Machines, of Which-the following is aspecification. This invention relates to heel-building machines, andconsists of a machine by which a heel is built up of a series of liftswhich are automatically assembled successively'. I

The assembling of the lifts in the illused by arranging in a series aplurality of lift hoppers or magazines, and moving a heel carrier so asto pass the magazines successively and take from eacha lift in such waythat it builds up into a heel pile those taken from the previousmagazines.

In addition to the mechanism for auto-' matically assembling the liftstofornraheel,

the inventionalso consists'of means for securing together the liftsforming the heel by applying cement to the lifts individually, and, as afurther. refinement,.means for finally securing together all the liftsof a built-up heelby drivin a fastener therethrough. I

order to permit the r variety of other embodiments in addition to thatillustrated. Inthis connection? particular attention is called to theuse, throughout Patented July 2c, 1915.: Application filed August-.16,1907. Serial No. 388,827. 3

the specification and claims, of the term".

lift to designate the layers or blanks of which the heel produced by themachine i. composed. The term lift is used herein in an inclusive senseas defining any blank or layer of material capable of being used. in

the formation of a heel pile, from which a heel' s ultimately produced,irrespectiveof the particular shape of the blank or the nature of thematerial of which it iscomposed. I

The same reference characters indicate the.

same parts'wherever. they occur.

In the embodiment of the invention illustrated in the-drawings l0 is a'bedplate,

above Which is aseries of magazines each open at the bottom and adaptedtoc'ontain a pile of heel lifts a. The bed plate 101's supported onlongitudinally extending frame pieces 11 and 12, which are supported inparallel relation .upon upright frame pieces l3, 13. The frame pieces 11and 12 are fOrmed Wit-h guides 1-1 1%, on which a carriage 15 is adaptedto slide back and forth under thelift magazines and below the bed plate.10. The carriage 15 is pro vidcd with a movable carrier .16 havingafinger 14' The series of magazines extends from which extends through alongitudinal slot 18 in the bed plate, and which is actuated so;

front to rear of the bed plate 10 sothat the carriage 15 passes underthem successively,

and they are arranged at successively greater heights above the bed.This arrangement of the magazines is forthe'purpose of permittinglthepassage thereunder of the increasingpile of lifts of which the finger l7removes one from. each magazine. Each magazine comprises a hopper 2-0supported on av two-piece bottom plate :19 of Which the two pieces areseparated by a.

' space s'ufiicientfor the passage therebetween' of the pusher finger14. -Each hopper 20 is adapted to contain a Y il the. lower mostlift,the'rear portion or. the bottom edge pile cflifts, and,.in

of the hopper is cut away as indicated in Fig. 3, by the numeral 21. Theouter edges of the bottom plate 19 are aflixed to vertical adjustableblocks 22 mounted on brackets 23 spondingly elevate the finger 17 stepby step as it advances, so as to cause it to engage the edge of thebottom lift of each magazine.

For this purpose. the carrier 16 is provided with trundle rolls 25 whichrun upon tracks 26. The plane ofthe tracks immediately below themagazines is preferably parallel with the path of movement of thecarriage, but-inclined between the magazines so as to cause the rolls 25and carrier 16 to rise be-.

tween each two adjacent magazines. The drawings (Figs. 1 and 3)illustrate tracks made in sections, comprising. adjustable members 27and hinged connecting members 28. The adjustable members are mounted onadjusting stu ds 128 withwhich they have screw-threaded connection, thestuds being stepped in bearings on longitudinal rails 29, of which oneis aflixed to each of the side frames 11 12 (see Fig. 2). The carrierl6is so mounted in the carriage that it is moved longitudinally of themachine by the carriage and relatively to thecarriage by the tracks 26which elevate it, while a spring 30,

interposed in the carrier and engaging a portion of the carriage, tendsto move the carrier in the opposite. direction so as to hold the rolls25 against the tracks.

In the operation of building up a heel of lifts a contained in theseveral magazines, the carrlage 15 starts from the position 1n which itappears in Figs. 1 and 3, and moves from left to right, or from front torear of the inachine. Although there are ten magazines illustrated, itis not intended that the invention should be limited to that number.Assuming that it is desired to build up a heel havingten lifts, themagazines 20 and the ,carrier' tracks 26 are adjusted so as to cause thefinger 17 to engage and remove the bottom lift from each of the piles inthe magazines. Movement of the carriage causes the finger v17, whichextends through the slot 18 in the bed, to pass betweenthe two halves ofthe supporting plate 19 of the firs; magazine and to abut against theedge of the bottom lift a'bf that pile. The finger continues to move'under the second lift of the pile meanwhile pushing the bottom liftthrough the opening 21 at the rear of the magazine. As soon as the firstlift is pushed beyond its plate 19, it lies upon the bedplate 10,bridging the slot 18 on which it is guided from one magazine to the nextby guide plates 31 which prevent the lateral displacement of the lift.The latter are provided with slots giving them a range of adjustment sothat they may be clamped on .the bed by their screws 33 so as toaccommodate lifts of anydesired width, see Fig. 7.

'As the finger 17 passes to the second magazine, the rolls 25 of thecarrier pass over the first pair of hinged members 28 of the tracks 26to the first pair of adjustable members 27, which are at a higher planethan that portion of the track under the first magazine. The inclinedportions 28 cause the rolls, together with thecarrier 16 and finger 17,to rise relatively to the bed 10 and the first lift thereon. Theelevation of the portions 27 is such as to cause the end of the finger17 to rise above the top of the first lift almost if not quite as muchas the thickness of another lift. Continued movement of the carriagethen causes the finger 17 to push the first lift under the relativelyelevated supporting plate 19 of the second magazine, whereupon the nowelevated finger abuts against the edge of the bottom lift of the saidhopper. The last named" lift is then pushed through its outlet 21, and,when free of its plate 19, it lies upon the lift which was removed fromthe first magazine. The carriage advances, passing successively underthe magazines, the finger 17' meanwhile rising step by step, andremoving the bottom lift from each magazine as described in connectionwith the first and second magazines.

zines and having removed a lift from each, thefinger 17 pushes the pileof ten lifts a short distance beyond the last magazine as shown at 0Fig. 6, where it subsequently receives a nail to bind the liftstogether. Thus the withdrawn lifts are transferred to a common point. Asthe heel 0,-shown in Fig. 6, is built up of lifts of different sizes,-itwill be apparent to thosev skilled in the art that the ten magazineshereinbefore described are constructed'tohold stacks of order to permitthe machine to build heels having all, or a portion of itslifts, of thesame size, the magazines are removable and After having passed all ofthe maga-' heel lifts of different sizes respectively. In

interchangeable by simpl unscrewing the studs 24, see Figs. '2 and sothat any desired combination of lifts may be assembled in a pile.Although the drawings illustrate s'omewhat'conventionally a convenientform ofnailing mechanism, the-latter is not essential as a.- part of aheel-buildin machine; for it will be understood that, .lnstead of that,the heel lifts might be fastened by a nail driven manually. The lastpair of guide plates '31 are provided with spring clips 3i which holdthe lifts intact in the form of a heel during the operationof thenailing mechanism hereinafter described. Meanwhile the carriage 15returns to its initial position so. as to repeat the building ope?ation.During the return trip of the carriage, the finger '17 again engages thenow bottom lifts in the magazines, but it is ineffectual by reason ofbeing mounted so as to be displaced by them. The finger is shown inFigs. 2 and 3 as being mounted between two ears and upon a pivot 36extending therethrough. Shoulders formed on the under side of the fingerare adapted to engage the supporting carriage, and,

while they permit a certain amount of tilting movement of the finger,they limit the same so that the finger cannot tilt forward when setatits initial position as in Figs. 1 and 3. It can, however, tiltrearwardly from this position, but, with slight friction which isafi'orded by the ears 35, it remains in whatever position it is left.Inreturning to the front of the machine after leaving a heel between theclips 34, the finger 17 is caused by its'engagement with the bottom liftin the rear magazine to tilt rearwardly until its free end dips belowthe lift, and so to dip step by step as it engages each succeedingbot-tom lift. After passing the forward magazine, a nose 37 formed onthe finger abuts against an adjustable stop 38.

by means oi which the finger is tilted forwardly and upwardly to itsoriginal upright positio a. The finger is then in operative positionready for the next trip of the carriage toward the rear of the machine.

Any form of mechanism may be employed to reciprocate the carriage 15 inits guides 24, that here n shown comprising cords 4:0 (or other flexiblepower transmitter) which pass around .dle pulleys ll 41. The outer endsof the Cords 4O 40 are attached to the carriage. and their inner endsare made fast to a driving pulley The latter is affixed upon a rotatableshaft 43which is driven alternately in opposite directions. F or thispurpose the shaft is provided with a pinion 44 which intermeshes with areciprocatory rack The rack is pivotally connected to one end of apitman' 46 whose other end is 'OIII'IBCtQd to a crank 47 formed on apower shaft 4-8. 49 and 50 are the pulley and bolt by which the shaft 43is rotated continuously in one direction, transmitted to the shaft 43bythe roman .ions described in the form of osill rim '1 uweincnt.

is a detail of construction, each lift magazine 2O isprovided with. anadjustable gate 51 (see Figs. G and L for g'a-ging. the deptn of theopening through which the lifts L-arc removed. The gate is clampedactuated so as to drive a nail into the hefi deposited between thespring clips 34. It includes a reciprocatory driver 55 a nail hopper 56,a. delivery nozzle 57 and a race 58 for conducting the nails F) from thehopper to the nozzle. Although it is not shown in detail, it may bepresumed that the hop per 56 is provided with a. feeder for placing thenails in the race.

mounted. on YuTQClPI'OCfitOl'V crosshead or yoke 59, and its free end isguided toward The driver 55 is i and from the work in the throat of thedelivery nozzle 57. interposed between the throat of the nozzle and therace is an osci1- v latory picker 60 having a notch 61 which receivesthe foremost nail in the race and transfers it to an aperture 62 in thenozzle. 'A'nail placed in this aperture gravitates into the throat ofthe nozzle and finally descends to a divided nail holder comprising thetwo halves 63 63 (see Fig. 7). Each half is pivotally mounted on a fixedstud 6d and provided with a segment of teeth which intermesh, so thatmovement of one half communicates movement to the other half. A spring66 holds .the halves normally so that the supportin ends abut againsteach other. Each of the latter ends has a tapered notch 67 on itscooperative face, the two notches forming a split pocket into which, thepoint of a nail may rest until driven. The nail holder is locateddirectly above the built-uoheel, so that, when the driver 55 descendsupon the nail therein, the point of the latter wedges apart the halvesof the holder and enters the heel. For oscillating the picker 60 so asto place the nails one at v oncoming nail'in the aperture 62 isprevented by the driver from entering the throat until the driver againrises. When it does rise above the aperture 62, the nail containedtherein gravitates to the holder 63 and is ready to be driven into thenext heel.

The crosshead 59 is mounted upon and reciprocated by a pair of parallelrods 70 .70 which move in bearings 71 on the frame. The rods areprovided with collars 72 and helical springs 73 which exert theirtension against the collars to depress them and drive the nail.Automatic mechanism is employed to raise the rods 70 and driver againstthe tension of the springs 73, and to release the same when a heel isplaced under the nailing mechanism. For this purpose, the rods areconnected by another yoke or crosshead 74, whose ends move in guides 75,and which is connected midway between its end to one end of a pivotedlink 76. The other end of the link is connected to one end of a rockingbeam 77 fulcrumed at'78. The other end of the beam is pivotallyconnected by a link 7 9 to a crank 80 formed 011 a rotatable shaft 81.The shaft is provided with a loose sleeve 82 having a pulley 83 and aratchet 84. The sleeve 82 is continuously rotated in one direction asindicated by arrows in Figs. 1 and 11, by reason of being v the latterso as to normally cooperate with connected to the prime shaft 48 by abelt 85 passing over the pulley 83 and over a pulley 86 mounted on thesaid shaft. The shaft 81 is also provided with a tight sleeve 87 onwhich is pivotally mounted a pawl 88 adapted to coiiperate with theratchet 84. A spring 89, engaging a nose of thep'awl, tilts the ratchetand transmit rotation thereof to the shaft 81. An arm 90, pivoted on astud 91, is adapted to engage the pawl and disengage it from theratchet. The free end of the said arm is adapted to rest upon theperiphery of the sleeve 87 and to move it into the path'of the pawl whenthe sleeve revolves. The pawl abuts against the end of the arm and istilted thereby against the tension of the spring 89 so that it becomesdisengaged from the ratchet. A shoulder 92 on the sleeve then abutsagainst the pawl 0pposite the arm 90, and rotation of the sleeve andshaft 81 is arrested. The pawl is preferably located with relation tothe crank 80 so that it engages the arm 90 immediately after the crankhas passed the dead point at the completion of the up stroke of the rods70. The springs 73 are then exerting their tension to force the rods 70downwardly and to rotate the shaft 81 in the same direction in which theratchet 84 rotates. The pawl 88 is hereby held in engagement with thestop arm 90 and out of engagement with the ratchet until otherwisereleased."

For releasing, the pawl, the stop arm is provided with a boss 93 whichcoacts with the hooked end of a bell crank 94: pivotally mounted on thefree end of an arm 95 The arm 95 is aflixed to one end of a rock shaft'96 on the other end of which is an arm 97 by p which the shaft isrocked. The free end of the arm 97 lies in the path of movement of a I1,me,996.

nose 99 formed on a reciprocatory rod or actuator 100 extendinglongitudinally of the machine and mounted in brackets 101 on the frame.See Fig. 2. The ends 102, 103' of.

guides 14 engages first one and then the other of the ends 102 and 103and thereby then in the opposite direction. \Vhen it moves to the rearof the machine and deposits a built-up .heel 0 under the nailingmechanism, it engages the end 102, moving the actuator a short distancewith it. This causes the nose 99 on the actuator to. engage and movethefree end of the arm 97, thereby rocking the shaft 96 so as to elevatethe arm with the bell crank 94. The hooked end of the latter, whichunderlies the boss 93, raises the free'end of the stop arm out ofengagement with the pawl 88. mechanism is thereby released and thesprings 73 then depress the rods 70 together with the driving head 59and effect the driving of a nail into the heel just placed under thenailing mechanism. The bell crank 9% in its upward movement engages afixed stop The nailing moves the actuator first in one direction and I105 by whichit is tilted so as to release the boss onthe stop arm 90.The stop arm then drops back until its free end strikes the sleeve 87upon which it rests once more. The ratchet 84: meanwhile continues tore- 'volve and picks up the pawl 88 by which it is again engaged. Itturns the pawl to-' gether with the sleeve 87 until the former onceagain strikes the stop'ar'm by which it is arrested as hereinbeforedescribed. The

nailing mechanism has then completed its cycle of movements and isreturned to itsnormally operative position. The carriage 15, when itapproaches its initial position,

engages the end 103 of the actuator 100 and moves the latter so that itsnose 99 leaves the rock arm 97 The weight of the arm 95 then causes it,together with the rock shaft and the arm 97, to assume their initial positions as illustrated by Fig. 1. In so doing, the bell crank 94 assumesits tripping position relatively to the boss 93, and all is ready to beagain released when the heel carri 1' shall have deposited another heelundert. e nailing mechanism. a

The invention involves, as hereinbefore stated, means for applyingcement 'to the lifts, and this is done, exceptin in the case of the lastmagazine, as each 1i t is removed from its hopper. The reason foromitting is because the only surfaces requiring cement are those whichlie-against other lifts, the

lift from the last magazine "being on the top of the heel and upon thecement-coated sur-.- 'face of the lift below it. a"

Each magazine is provided with a cement brush 106 so mounted that itsbristles wipe the upper face of each lift a as the latter is movedthrough the outlet 21 of its hopper during the operative trip All of thebrushes,

occupy positions adjacent of the heel carrier,

' the outlets of their respective hoppers, and,

trip of the carrier, they during the return are moved laterally intoengagement with a cement roll 107 from which they receive cement. Figs.2 and 7. The roll 10'? and the cement trough 108, in which it isjournaled, are supported at one sideof the machine and extendlongitudinally thereof. A belt 109 passes over one end of the roll andover a pulley 110 on the prime shaft 48 and imparts rotation to the rollwhose under side is kept immersed in cement. y Inasmuch-as thecement-applying devices of each magazine are identical, a description ofone will be sufficient. The stem of the brush is rigidly mounted in alaterally-extending reciprocatory rack 111 mounted in hearings in thebrackets 23. The teeth of the rack intermesh with a pinion 112 mountedon the upper end ofa perpendicular shaft 113 which is journaled in thebrackets 23 and 101, the latter, as hereinbefore stated, supporting theactuator 100. The lower end of the shaft has a pinion 114which'intermeshes with rack teeth 115 formed on the actuator 100 bywhich it is rotated alter nately in opposite directions. All of theshafts 113, being arranged and actuated by the actuator 100 as shown byFig. 5, causethe cement brushes 106 to move simultaneously to a positionabove and in engagement with the cement roll when the heel carrierdeposits a heel under the nailing mechanism. In this position thebrushes remain While the. heel carrier is returning to initial position.The cement roll meanwhile revolvesthereby filling the brushes withcement until the carriage 15, at the end of its return trip, moves theactuator in the opposite direction. The brushes 106 are then moved totheir operative positions adjacent the openings 21 of the hoppers.

lVhile this specification and the appended claims refer to removin thelifts from the magazine singly or one at a time, I do not mean therebyto limit the invention to removing only one lift from each magazine, astwo or more might be removed from each magazine for a dry or unpastedheel,

without materially changing the construc-' tion offthe machine,.andhence I desire to have those terms construed in the light of thisexplanation.
